A real-world case involving Russian hackers who stole $100 million from Wall Street illustrates the risks: they used a small VPN provider (AirVPN) with few clients, making traffic correlation easy for the FBI, and they logged into personal Apple accounts while connected to the VPN, directly revealing their identity. The key takeaway is that VPN anonymity depends on never linking personal accounts to a VPN session and choosing providers with large user bases to obscure traffic patterns. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How did the FBI catch a hacker who was using a VPN to hide insider trading activity? The hacker used AirVPN, a small VPN service with only a few hundred clients, making it easy for investigators to correlate exit node traffic timing with the timing of suspicious stock trades. The fatal mistake was logging into a personal Apple account while connected to the VPN, which directly linked the anonymous traffic to the hacker's real identity, leading to their capture after stealing around $100 million from Wall Street trades. _Anyone relying on a VPN for anonymity can find real-world opsec failures and lessons discussed on daily.dev._ ### Why does using a small VPN provider make it easier to get identified compared to a large one? A small VPN provider with only a few hundred active clients produces a narrow pool of traffic, so investigators can more easily correlate exit node activity with a specific time window, such as when suspicious trades occurred. Larger VPN providers with millions of users create far more noise, making it much harder to isolate one person's traffic from everyone else's. _Developers weighing VPN providers for privacy can dig deeper into these tradeoffs on daily.dev._ ### Why is it a mistake to log into personal accounts while connected to a VPN meant to protect anonymity? Logging into a personal account like Apple while connected to a VPN ties the supposedly anonymous VPN traffic directly to a real identity, since the account login reveals who is behind that connection at that specific time. This single action can undo all other anonymity measures, as it was the key mistake that led to a hacker's capture despite otherwise concealing insider trading activity. _Anyone building a real privacy or opsec habit can compare mistakes like this on daily.dev._ --- Tags: [#security](https://daily.dev/tags/security), [#vpn](https://daily.dev/tags/vpn) [View this post on daily.dev](https://daily.dev/posts/vpns-won-t-make-you-invisible-3hmbshvww) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"VPNs Won’t Make You Invisible","url":"https://daily.dev/posts/vpns-won-t-make-you-invisible-3hmbshvww","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/vpns-won-t-make-you-invisible-3hmbshvww"},"datePublished":"2026-07-13T20:35:19.659Z","dateModified":"2026-09-13T20:40:48.215Z","description":"VPNs are widely marketed as ultimate privacy tools, but two critical mistakes can completely undermine their effectiveness.
